I have a weird display issue on my Gottlieb Genesis, where after boot, both display's work, but after about 10-12 seconds, the lower display goes and stays dim. It does it exactly the same and at the same time every time the game is rebooted. You can see the text on it, it's just really dim.
The board has had all caps replaced and has been tested.
The cables have been re-seated.
What else could be causing this issue?
